To @ZZ miao/"n, it nca-g concern/2,: ABe itknown that I, PHILIP Li. PAssAvANT,

' acitizis of the United States, residing at Conuellsville, in the county of Fayette and State-of Pennsylvania, have invented a new anduseful Automatic Lubricating Device', of which the following is a specification.

My invention relates to greasc-cups or lubricating devices in which the lubricating material, in the forni .of a semi-solid stick or'cartridge, is automatically ,fedand applied to the 'ournal box or bearing to be lubricated wJhere it becomes liquefied by friction.

The object of my ini'fcntionis to provide ia. device of this character'whereby the lubrieating cartridge or stick. is automatically and continuously fed, under spring pressure,

`upon the-journal box or bearing as. the saine may be worn off or exhausted by the action ofthe bearings.

Another object of my invention is to provide simple and efficient means for coinpressing the spring. to permit the introduction ofa freshcartridge to renew the supply of lubricant material, anda further object thereof is to provide a more simple and effective mechanism ltc accomplish the above 'results which may be readily .applied to j our .nal boxes and bearings without aifecting their usual construction and operation, and

" which will keep theni thoroughly lubricated without any loss or waste of the lubricating material o'r possibility of running dry with the consequent heating of the parts, thus effecting a great economy inthe use of the lubricant material, reducing wear on the journals by friction, and rolonging the period for which a charge o lubricant cartridg'e will supply the bearing without renewal; 1

To this end 'the invention includes ther combination and arrangement 4of component parts to be hereinafter described and' particularly pointed out in the claims.

In the accompanying drawings, Figure 1 isa vertical sectional view of my lubricator attached to the crank-end of a shaft showing the lubricator charged. with a lubricating v cartrid e under spring pressure; Fig. 2 is a 50. v*com ressed to permit the introduction of vertice. sectional view showing the spring the ubricant cartridge; Fig. 3 is adetail view of the cylinder cap, spring and plunger;

and Fig.. 4 is a perspective view of the key lused' for compressingT the spring and plunger.

The invention includes generally a case, preferably of cylindrical form, adapted to contain the lubricant, provided with a suitable bushing and jam-nut, a plunger carried within the case, a coil spring interposed -between the plunger and a suitable cap for the case, and bearing upon said plunger and cap, and a detachable stein for compressing the spring between the permit the insertion of cant in the case.

Referring to the drawings, l designates a plunger and cap to t ie charge of lubrimoving journal box used for connecting rods in which 2 indicates the crank pin, 3 the brasses and 4 the strap whereby the brasses are confined and secured to the driving shaft. I

5v designates the lubricant case, which, as shown, is preferably of cylindrical form, having its lower exterior screw-threaded at 6 to receive the .bushing ".7 and jam-nut 8. Said bushing isv internally and externally threaded and is provided with the angular nut-head 9. As shown. in the drawings, the bushing is screwed into an annular collar 10 on the strap 4, and the case 5 is screwed down `into the bushnig until its lower end is adjacent to or rests upon the strap. A lubricant channel 11 communicates through the journal box with the bore of the lubricant case 5 and the journal bearings or crank-pin 3. When the lubricant case and bushing are in the positions above described, they -may be locked therein by tightening the jam-nut 8 upon the head of the bushing.

The inner wall of the cylindrical lubricant case 5 is provided., adjacent to its lower end, with an inwardly extending annular flange 12 which forms an annular shoulder 13 adapted to forni a seat for the lubricant car-- coil spring 18.

Y the lubricant is graduallv and automatically the bore of the lubricant casc. The lower :face of said plunger is adapted to bear upon the lubricant cartridge, and .itsupper face is provided with an annular head 16, ,of lesser' diameter than. the plunger, which head is surrounded. by the annular shoulder i7 forming a bearing for the end of the coil spring 18. The head 16 Vof the plunger is provided with a lateral extension or ear 19, which is pierced transversely by t'lie circular orifice 20, which as shown, is squared at its upper side to rio-act with a hook hereinafter fully described.

The lubricaruv case is closed by the cap .15,wliicl1 also fr. 'is the top bearing for the cap con'lprises the nut head 2l. on its upper face and the screwthreaded annular extension 2li which screws intothe internal threads adjacmit to the top Vof the cylindrical case 5. Ther-ap' is pro vided'witli a central'bore 24 which is Seur-- rounded by the annular longitudinal flange 25 von the lower tace of the cap, which 'forms the annular shoulder 26 adapted to forni a bearing for the 'upper end of the coil spring7 18, which is interposed between the ]ilunger 14 and the cap 15. From the accompanying drawings and 4the foregoing description, it will be apparent that the cylindrical case 5 is adapted to contain a lubricant cartridge 33 beneath. the spring pressed plunger 14, as shown in Fig. 1 of the drawings, by the action of which su plied to the journal bearings.

lor the purpose of compressing the spring and plu-nger and holding same topernn't the.

lling ofV the lubricant case, the plunger is provided with a detachable stern 27 compris ing the screw-threaded shank 2S and the `ho'olred end 29. lThe hooked end of the stein fits withinrthe orifice 20 in the head of the plunger 14, and the screwthreaded shank projects through the bore 24 in' the cap 15,' and carries the cranlenut 30 on .its outer end.

cylinder. Tbe capunay' then be replaced on the caso and the .plunger and spring released by unscrewing the eranlenut,l thus releasing Vthe pressure of the springr upon the lubricant charge, and the plunger stern may, if desired, be detached from the plunger and removed from the case. i

Having thus described my invention, what l claim as new and desire to be secured by Letters Patent, is

l. .nn automatic lubricating device con1- prising a lubricant containing case, a spring` vactuated plunger 'within the oase having a hea-d on its upper .si de, and a detachable stem for the plunger, there being a non-threaded connection between said bead and the stem, substantially as described.

i2, An autonmtic lubricating device coni# prising a cylindrical case ada ted to contain a lubricant cartridge, a pertorated cap for said case, a spring-actuated plunger within the ,case provided .with a transversely perfoated head. and a detachable stein 'lit-ting therein, substantially as described.

combination. with a lubricant containingcase, and a perforated cap therefor, of' ja spring-actuated plunger within the caseprevided with a transversebT perforated head, a

detachable screw-threaded stern. having' ar hook at one end adapted to engag'efthe perfo rated bead of the plunger, and a crank-nut upon the opposite end, substantially as described.

In testimony whereof l have signed my naine to this specification in the presence of two subscribing Witnesses.
